Gulp / Node设置

//default
browserSync({
    proxy: "localhost:"+config.port,
    port: 4004,
    open: false,
    files: [
        gulpConfig.paths.public + gulpConfig.paths.css + gulpConfig.filenames.css,
        "./client/js/**/*.js",
        "./index.html",
    ],
    reloadDelay: 100
});

//browser.js
var gulp = require('gulp');

gulp.task('dev',['watch', 'js'], function () {
    var nodemon = require('gulp-nodemon');
    return nodemon({
        script: './syndshare.js',
        watch: './lib/'
        , ext: 'js html'
        , env: { 'NODE_ENV': 'development' }
    }).on('start', function () {
        console.log('MOL-fe-brexit has started');
    }).on('quit', function () {
        console.log('MOL-fe-brexit has quit');
    }).on('restart', function (files) {
        console.log('MOL-fe-brexit restarted due to: ', files);
    });
});

Syndshare.js

var express = require("express");
//var https = require('https');
//var http = require('http');
//var fs = require('fs');

/* #Load configurations with npm config ----------------------------- */
var config = require('config');

/* #Set up App ------------------------------------------------------ */
var app = express(); 

/* #Express Setting ------------------------------------------------- */
require('./lib/express')(app, config);

/* #Routes ----------------------------------------------------------- */
require('./lib/routes')(app, config);
require('./lib/auth')(app, config);

app.listen(config.port, function () {
    console.log( 'METRIC ns="syndshare" name="start" port="' + config.port + '"' );
});

process.on('exit', function () {
    app.close && app.close();
});

process.on('SIGINT', function () {
    process.exit(2);
});

无论我改变什么端口都不会运行。我想让服务器运行。
